摘　　要：针对产品的非圆曲线几何轮廓加工,提出一种基于逼近误差的最佳逼近点搜索算法,实现了非圆曲线特征信息完整保留。研究了集成曲线逼近加工策略的数控自动编程系统,能自动识别非圆曲线、圆弧以及直线,自动生成的数控加工代码可在多系统的数控机床上应用,提高了复杂产品的加工效率和精度。Aiming at the geometric contour machining of the non-circular curve,an optimal approximation point search algorithm based on error control was proposed,by which whole information of non-circular curve could be contained.An automatic NC programming system was developed,which integrated the non-circular curve approximation machining strategy,could automatically identify the non-circular curve,arc and line.The NC code can be used in multi system CNC machine tools,and can improve the efficiency and accuracy of complex products processing.
